\n" ); document.write( "------------------
\n" ); document.write( "2x+5y = -2
\n" ); document.write( "x = 10-8y
\n" ); document.write( "----
\n" ); document.write( "Substitute:
\n" ); document.write( "2(10-8y) + 5y = -2
\n" ); document.write( "20-16y+5y = -2
\n" ); document.write( "20-11y = -2
\n" ); document.write( "11y = 22
\n" ); document.write( "y = 2
\n" ); document.write( "----
\n" ); document.write( "Sinc x = 10-8y, x = 10-16 = -6
